What is a Hash Algorithm?
A hash algorithm (or hash function) is a mathematical function that takes an input (or message) and returns a fixed-size string of characters, which is typically a digest that appears random. It is widely used in computer security, cryptography, and data integrity. Key Characteristics of a Hash Algorithm:
Deterministic: Same input always gives the same output. Fixed Output Size: Regardless of input size, output length is always the same. Example: SHA-256 always returns a 256-bit hash. Fast Computation: Efficiently computes the hash value for any input.
Pre-image Resistance: It is hard to reverse-engineer the input from the hash. Collision Resistance: Two different inputs should not produce the same hash. Avalanche Effect: Small changes in input produce drastically different hash outputs.
